Sliding Display Cradle for Portable Terminal Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional portable terminals require separate, cost-ineffective cradles for convenient viewing, are inconvenient for game functions without cradles, and have structural limitations that hinder miniaturization due to thick and voluminous designs.
Innovation Solution
A portable terminal with a recessed housing allowing the display unit to slide and automatically rotate to a predetermined angle, using a sliding type cradle that reduces part count and mounting space, enabling miniaturization while allowing easy viewing of TV programs and reducing terminal size and volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate cradle is used to support the portable terminal at a slant for convenient viewing, then the viewing convenience is improved, but the cost increases and the device complexity increases
Solution Approach 1:
The patent merges the cradle function with the terminal housing itself by forming a recessed space that receives and supports the display unit at a slanted angle. This integration eliminates the need for a separate external cradle while maintaining the viewing convenience benefit.
Solution Approach 2:
The display unit is nested within a recessed space formed in the terminal housing. This nesting arrangement allows the display unit to be supported at a slanted angle for convenient viewing while being contained within the terminal's own structure, avoiding the need for external support devices.
2Stability of the object's composition
If the portable terminal is designed with thick and voluminous structure to accommodate conventional display positioning, then the structural stability is improved, but the terminal size and volume increase
Solution Approach 1:
The patent transitions from a flat, planar display positioning to a three-dimensional slanted configuration by forming a recessed space with depth. This dimensional change allows the display unit to be positioned at an angle for stable viewing while maintaining a compact overall terminal volume.
Solution Approach 2:
The patent changes the spatial parameters of the display unit positioning by creating a recessed space with specific depth and angular orientation. This parameter modification enables the display to be held at a stable slanted angle without increasing the terminal's external dimensions.
3Volume of moving object
If the display unit is positioned flat without a slant for compact design, then the terminal volume is reduced, but the viewing convenience deteriorates
Solution Approach 1:
The patent creates a dynamic viewing configuration by forming a recessed space that naturally positions the display unit at an ergonomic slanted angle. This dynamic geometric arrangement provides optimal viewing convenience while maintaining compact terminal dimensions.
4Ease of manufacture
If conventional flat display positioning is used to simplify the structure, then the manufacturing ease is improved, but the viewing angle and user comfort deteriorate
Solution Approach 1:
The patent applies local quality modification by forming a recessed space with specific angular geometry in the terminal housing. This localized structural feature provides optimal viewing comfort at the display position while maintaining overall manufacturing simplicity through standard molding or machining processes.

AI summary
Disclosed is a portable terminal and a sliding type cradle for the same, by which a user can conveniently view images. The portable terminal includes a first housing having a recess formed at a desired depth on an upper surface of the first housing, and including at least one speaker unit and a plurality of keys; and a second housing including a display unit, and sliding while facing the first housing and automatically rotating at the location where the sliding movement terminates so that the display unit is slantingly cradled.
